ASpecification of Letters Patent.

Patented May 2e, 1907.

Original application iiled February 3, 1906, Serial No. 299,242. Divided andithis application l'lled May 1B, 1906. Serial Nb. 317,510.

To all whom it may concern.-

Be it known that I, HARRY B. ARDEN, a citizen of the United States, and a resident of the city, county, and State of New York, have invented anew and useful Improvement in Conveyers, of which the following is a specification.

This is a division of my application No. 299,242, filed February 3, 1906.

The object of my invention is to provide an apparatus of this class which will always carry away and dispose of allearth or dirt disturbed by an excavator and do this regardless of the speed with which the excavator is operated or the particular part of the cut wherein it is located.

1n the embodiment of my invention which accomplishes this object, the shovel or eX- cavator is suitably mounted and connected with a conveyer of a peculiar type as will hereinafter appear. There are also certain improvements in details of construction incidental to the main invention as will also hereinafter appear.

For a more particular description 'of my invention reference is to be had to the accompanying drawings forming a part hereof in which:

Figure 1 is a side elevation of one form of my apparatus. Fig. 2 is a section through the conveyer showing the manner of supporting and connecting the buckets. Fig. 3 is a plan view of the hopper. Fig. 4 is a perspective view of one bucket. Fig. 5 is a side elevation of a different arrangement of conveyors. Fig. 6 is yet another modification of my improved conveyer. Fig; 7 is a portion of a more or less horizontal conveyer mounted on trucks to move laterally. Fig. -8

is an elevation of the pivotal portion of the structure shown in Fig. 6.

Throughout the various views of the drawings similar reference characters designate similar parts. The various features of my invention may be embodied in many forms,

' diiering somewhat in details, but all havin features in common.

Inthe modiiication 'ing carried by suitable trucks 1a, on aV transverse frame 4 carried by trucks on the longitudinal tracks 5 and 6, the other end of the 5 5 conveyer 3`being supported, by a pier 7.

vwhich pass beneath it.

shown in Figs. 1 to 4 inclusive, the steamshovel 1 '1s shown mount.

mounted on a truck 8 which runs on a transverse frame 9 supported by two trucks 10 and 11 which in turn run on tracks 12 and 13 placed parallel to the tracks 5 and 6, but on the bank instead of in the cut 14. The conveyer 3 and frame 2 are flexibly connected by any suitable means, as a slot and pin connection 6.5. The soil or earth excavated by theshovel 1 is carried by the conveyer to its upper end and there dumped on the spoil pile A. As the conveyer 3 and shovel 1 are directly connected, they always have the same relative positions with regard to transverse and longitudinal movements, with the result that each is always ready to co-operate With the'other.4 y

From the' foregoing a general idea of my invention will be readily had. The details are for the most part of the conventional type and so only the novel features need be particularly pointed out.

Conveniently located at the lower end of the conveyer 3-.is a hopper or trough 15 whichis situated so that the shovelA 1 maydump into it. This hopper' 15 has flaring sides 16, 17 and 18 andfis'open at its bottom and upper end'and slightly narrower through this bottom than the cars or buckets 19 This hopper 15 is suitably and rigidly supported from the frame of the conveyer 3 and has suiiicient clearance over the buckets 19, but not suflicient to allow the dirt excavatedto drop through. The buckets 19 have a bottom 20 with a rear vertical wall 21 and two slde Walls 22 and 23, but no front wall. Each bucket has also three spindle lugs, the rear lower edge having the lugs 24 and 25 and the front edge having the lug lugs are so proportion'e the lug 26 of'each bucket vits between the lugs 24 and 25 of the bucket lmmediately in lfront and a common spindle unites'the three. At each end 'of each spindle are loose flanged wheelsv 27 that run on tracks 28 and l29 above and `below the axis of conveyer 3. By 'this means the buckets 19 are united into an end- 26. These spindle and arranged that IOO lesschain with flanged wheels supporting the same at each end of each link so thatthe chain may always move without delay or friction.` As the buckets have no front wall theymay be easily dumped. fMotion is imparted tothis endless chainby means of sprocket wheels 30 and 31 at each end ofthe conveyer which are rotated by any suitable means (not shown.) The vertical Walls of the buckets 19 come sufficiently close together to form practically contlnuous side walls until the chain is bent at one of the pairs of sprocket wheels at either end of the conveyer.

The bracing given to the `conveyer depends upon its size, length and shape.` It may be given any suitable form and is not necessarily straight, but as such details vare well within the skill of an engineer, it is not necessary to consider them here. Generally it is better te place horizontally disposed pivot 32 between the pier 7 and truck 8 vto allow for inequalities in the tracks 12 and 13. If these tracks are nearly or perfectly true this pivot 32 may be dispensed with.

From the foregoing the operation of this embodiment of my invention will be readily understood. The shovel 1 from time to time and as rapidly as possible empties into the hopper 15 andthe spoil passes into the buck` ets 19 which` run along the conveyer 3 and these buckets 1 9 are dumped when the bucket passes over the sprocket wheel '31. At all times the conveyer is ready to receive spoil from the shovel 1, and no matter how rapidly this shovel 1 is operated, the same condition remains, so that the shovel is never delayed by the conveyer. Nor is it necessary that the buckets 19 should empty onto a spoil pile, they may empty upon a conveyer 35 as shown in Fig. 7 which is carried by trucks 36 and this conveyer 35 may dump on a Waste pile not shown, or it may be carried to a thirdA conveyer 37 shown in Fig. 6, which is in turn carried by 'car 38 on a track 39 which car'38 also carries a pivoted hopper 40 fixed to a conveyer frame 41 and which turns under the conveyer 47. The conveyer frame 41 is pivoted at one end and' rests on a pier 42 supported on rollers 43 which run laterally on a car 44 which moves on a track 45 bent on thearc of a circle struck from the pivot ofthe car 38. The vconveyer frame 41 is .carried far and high enough to dump on a spoil pile- 4 6 which may be greatly removedpfrom thesteam shovel 1. As this shovel 1 Vadvances and forth and from time to time the track 4'5 is relaid to compensate for the forward move- 50 runs longitudinally of the cut and is fed by two or more shovels, not shown, the usual hopper 51 being employed. The conveyer that particular conveyer may be made to run itself and then b rakes may be needed, or it may be geared to some other conveyer winch is not downwardly inclined so that the con -veyers may be operated with la minimum power.

For some purposes it is essential to use the preclse form of conveyer herein described. For others, different forms may be employed .so that my invention in itsv broadestA aspects is not to be considered. as limited to the precise disclosure herein, but as broad enough to cover all structures that come within the scope of the annexed claims.

Having thus described myinvention what' I claim is 1. A series of conveyers,' each adapted to receive excavated materialfrom the preced-v ing conveyer or other source of supply, one of said conveyers being pivoted at' one end on a y pivot supported on a movable base and supported at its other end from a car on a curved track independent of said movable base whereby the last mentioned conveyer may b e dumped on a curved spoil pile.

2. In a device of the class described, a 'con-- veyer, longitudinal tracks, trucks carrying frames with transverse tracks on said frames, means for carrying the conveyer from said transverse tracks whereby it may have either a longitudinalor a transverse movement, and a horizontal pivotal connection between one' of said carrying means Vand said conveyer.

3. In a device of the class described, a conveyer, longitudinal tracks,r trucks carrying frames with transverse tracks on said frames, means for carrying the conveyer from said transverse tracks whereby it mayhave either a longitudinal or a transversel movement,

saidl conveyer carrying means having hor'- zontal pivotalconnections at both ends.v

4. In a device o1 the'class described, a con eyer, means forsupporting said conveyer sovr as to permit both longitudinal and transverse movements and a hopper supported above said conveyer, said hopper having an open bottom narrower than "the, buckets pf said conveyer.

\ 5. In a device ofthe class described, a

curved track," a seconda/track' extendingthrough the-center .of curvature of the curvedl IOO track but separate-from the same, a 'con-,-

veyer, means for supporting. one end of said? conveyer from said curved track, and movable means Jfor pivotally supporting the 'other end of said conveyer from'the other track. f

6. In a device of the class described,` a curved track, a straight track, trucks `on each of said tracks, a conveyer, means lfor pivotally supporting one end of said conveyer from the truck Vonsaid straight track, means for supporting the otherrend of the conveyer from the truck on said curved track, ,a sec-4 ond curved track and a straight extension of said curved tracks parallel with thefirst mentioned straight track so-that the conveyer may be moved so as to be supported bythe trucks on both of said'straight tracks, thenmoved longitudinally of said straight tracks, g

then have its free end moved over said secl ond curved track.

7. In .a device of the class described, a 2o curved track, a second track extending.

through the center of curvature of,`the curved track, a conveyer, a car on said curved track, rollers adapted to run laterally on said car, a pier mounted on saidv rollers which supports one end of the conveyer, a car on lsaid straight track and pivotal means for supportting the other end of said conveyer from said car.
